COVE.

SPECIFICATION forming part of Letters Patent No. 468,354, dated February9, 1892. Application filed April 22, 1891. Serial No. 389,929. (Nomodel.)

To all whom it may concern..-

Be it known that I, GEORGE S. MAYHEW, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented an Improved Cove, ofwhich the following is a specification.

My invention relates to coves for use between the walls and ceiling ofan apartment or chamber to convert square angles between the same intocurves; and its object is to provide an especially rigid, firm, solid,and durable cove which may be safely transported from one place toanother without danger of breaking and which may be easily and cheaplysecured in place in any room, and, further, to

provide means whereby a cove may be neatly secured in place and acontinuous curve imperceptibly merging into the plain surfaces formed.

My invention consists in a cove provided with a face-sheet of thickpaper having edges extending beyond those of the main part of the coveand adapted to be closely and neatly joined with the plain surfaces ofthe wall and ceiling; in a cove composed of a face and a back sheet ofthick paper and wood strips arranged longitudinally between the same,the parts being rigidly cemented together and the outer or edge stripsof wood having wedge shapes, whereby the edges of the cove are thinnedor tapered and made easier to join neatly with the wall and ceiling, andin special constructions and in combinations, all

as hereinafter described, and particularly 3 5 pointed out in theclaims.

My invention will be more readily understood by reference to theaccompanying drawing, showing a cove embodying my invention.

In the drawing, 2 and 3 represent the face and back sheets,respectively. Between these sheets are arranged the narrow wood strips4E,

embedded within the adhesive compound 5,

which firmly and rigidly secures the slats or strips 4 together and tothe sheets 2 and 3 of 5 thick paper, which paper is of thick straw,wood, or other pulp board, having in itself some flexibility, but stillbeing firm and stiff.

This cove is formed in a curved mold of the required size and shape, theparts being therein assembled and subjected to heavy pressure tosolidify the whole. After being ceiling obliterated.

subjected to pressure, or at the same time, this whole is thoroughly andcompletely dried, and

is henceforth extremely firm and solid and will not warp, shrink, bend,or bulge. Thus in general I provide a cove of an extremely light weightin comparison to these constructed of other material, while at the sametime being more durable, owing to its character, as above stated, and tothe fact that it will not crack and thereby destroy the appearance ofthe ornament arranged on the face thereof.

To facilitate the joining of the cove to the wall and ceiling and togive the corner of the room the appearance of a single and neatlycurvedsurface extending continuously across the ceiling and down the side ofthe room I so thin down the edges of my cove that they may be closelyjoined and the lines of demarkat-ion between the cove and the walls andAs seen in the drawings, the outer or edge strip 4"l1ave not therectangular form of the other strips, but are of a wedge shape crosssection. These strips are cemented in just as the others are and theedges of the back sheet 3 extend out and cover them, as shown in thedrawings, the paper being bent down fiat at these points andsubstantially into line with the wall and ceiling when the cove isforced up into place. Further, a still finer joint is made with eachplane surface by extending the edges of the face-sheet out beyond themain or back portions of the cove. \Vhen the cove is manufactured, theseextended edges 0, owing to the stiffness and elasticity of the paper, donot conform to the curveof the rest of the cove, but extend outtherefrom at tangents to the same; but when the cove 0 is pushed up intoplace in the angle of the room these edges, striking the wall andceiling first, are forced back into or nearly into the true curve. Eachextended edge is shaved down on the back, so that very thin and pliableextreme edges are formed, which, owing to the spring or stiffness of thethicker part of the extended edges are forced into very close contactwith the wall and ceiling, although the latter may be quite rough andICC irregular. The edges are thus made so thin and fine that the linesof demarkation are the face of the cove is decorated.

' rectly back of the joints.

not perceptible, and when the ceiling, cove, and wall are papered orotherwise decorated a single curved surface is presented. Puckering orwrinkling while the edges are wet is prevented by the stiffness of thethicker parts thereof.

The cove is fastened by nails or tacks driven through the strips nearestthe edges, some adhesive material being first placed on the back of eachedge before the cove is nailed in place. The nail or tack heads sinkinto the soft thick paper and are not visible after H The thin pliableedges are then pressed closely into contact with the wall and ceilingand substantial and lasting joints thus completed. In some cases properadhesive compounds may be relied upon to secure the cove permanently inplace.

In the drawings I have indicated a decorative substance 7, secured onthe face of the cove, to which it is readily applicable, owing to thefact that the paper used is heavy and coarse, and it is obvious that theface-sheet ot' the cove may be painted or printed or otherwise decoratedand ornamented or made fire or water proof to correspond with otherparts of the building.

In practice I secure the abutting ends of the sections of cove withcement and upon suitably-curved bracket previously and carefully securedin the angle of the room and di- The other parts of the cove need nosuch support.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. The combination, in a cove, of thick sheets of paper-board with theparallel wood 0 strips arranged between the same, the edge stripsbeingwedge-shaped and the whole ce-.

theextension-edges are formed, the same be- W ing adapted to springfirmly into contact with the wall or ceiling when the cove is placed inposition, substantially as described.

4:. The combination, in a cove, with the two sheets of thick heavy paperor other pulpboard, of parallel wooden strips or slats arranged betweenthe same, the edge-strips having a wedge shape and the whole firmly andrigidly cemented together, the outer or face sheet of said paper beingwider than the other and the edges thereof extending or proje3tingbeyond the sa me, substantially as and for the purpose specified.

5. The combination, in a cove, of the sheets of thick paper with therectangular and Wedge-shaped strips 4 and 4, respectively arranged andcemented between said sheets, the outer sheet being wider than the otherand extending out and shaved to sharp edges adapted to make fine jointswith the wall and ceiling, substantially as described.

7 In testimony whereof I have hereunto set myhand this 16th day ofApril, 1891.
